[Should I make a bugreport with it on GCC/Bugzilla?]

From the sound of it, it should bzip fairly well.

I am very surprised by the difference of compilation time between 4.3 &
4.4.


  Me too.  I'm particularly surprised if none of the automated checkers have
spotted it, maybe there's something your code triggers that they don't
exercise, so you probably should file a PR.

I filled http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41971 with the bzip2-ed preprocessed warmelt-normal-1.i file

Regards.
